Boat’s Fuel Tanks Leak. Now What? Part 8 – Taco Marine Project Boat on Ship Shape TV

A leaky fuel tank needs to be fixed or replacedHaving fuel tanks that leak fuel is wasteful and dangerous. To test for leaks the TNT Custom Boatworks staff pressurized the Taco Marine Project Boat’s fuel tanks with 3 lbs. of air pressure and then went around the seams and weld joints with a soapy paint brush. Notice all the pin hole leaks causing bubbles around the seams. Older boats in use may have similar leak issues, so it is a good idea to have your boat checked. If left un-addressed, fuel leaks are bad for the environment and could be dangerous if not repaired. With the Taco Marine Project Boat going to a future owner, we chose to have new tanks made versus repairing the pin-holes. Make sure your new fuel tanks are built by a certified tank manufacturer so they meet specific US Coast Guard requirements. Check to see if your current fuel tanks have a seal or placard with a US Coast Guard Approval designation.

Boat fuel tanks are typically made from different gauges of aluminum, from 1/8th inch to 1/4 inch, depending on the sizFuel-Coatinge – in gallons, of your tank. An option for more protection to help prevent fuel tank leaks in the future, is to have them powder-coated, shown here on the left. With the boat being upgraded to best possible state, we opted to have our new tanks powder coated

Watch the video (Part 8), to see how the new fuel tanks were built and the options we had as the manufacturing process took place.

A couple of fuel tank sensor unit options discussed in the video are the Rochester Arm Sender unit that has been used for decades, and a Wema Fuel Level Sensor that slides up and down.
